Complete Your Rider Experience

Crank up steep climbs with smooth-rolling efficiency and swoop down singletrack descents with stability and speed. This aluminium hardtail 29er delivers a balanced ride quality on XC terrain.

Built on an ALUXX SL aluminium frame, Fathom 29 features updated geometry that produces a stable ride quality for challenging XC trails. The frame is optimised for a 100mm suspension fork giving you efficiency on the climbs and total control on the descents. A Giant Tubeless Ready WheelSystem comes with inner tubes in place, but the tyres and rims are tubeless-ready - a tubeless set-up ensures greater control and a reduced risk of flats on technical terrain.
